Claims priority, application Germany January 10, 1949 Claims. (Cl. 296-48) The present invention relates to a motor car body, particularly designed for motor cars of the constructional cell type, which comprises a roof, side walls, a floor, and transverse closing walls. These transverse walls serve to close the constructional cells, to support same and/ or to connect them to one another.

This invention is essentially characterized by the fact that the car body consists of a base portion and a top portion, the latter being constructed separately from the former, and that the transverse terminal walls provided at the two ends of the car body, together with the floor, form the base portion, whereas the side walls, together with the roof, form the top portion of the car body. Since the transverse walls used in vehicles of the constructional cell type, are designed to support the cells and to connect them to the adjoining ones, it is in this case, expedient to so design the transverse walls for them to constitute particularly strong bearing and supporting elements, and, if required, for example, with bodies made of artificial resin, to manufacture them in another material than those used in the construction of other bodies. This invention offers moreover the possibility to manufacture the transverse walls integral with the floor, which results in a reciprocal stiffening of these two parts. Furthermore, the weight of the top, which is properly speaking the body, will be reduced by the weight of the closing walls, thus reducing the strains acting at the supporting points of the car body. Another advantage of the invention will be that due to the separation of the transverse walls from the body upper part, the shape of the latter and hence its construction will be rendered much simpler.

Simplification of construction may be still increased, if desired, by a longitudinal or transverse division.

A further advantage will moreover consist in that in case of damage of the car body, a replacement of the upper part only, without the transverse walls, will generally sufiice.

In the attached drawing Figure 1 illustrates in perspective a first embodiment in accordance with the present invention showing diagrammatically the main features of the invention and Figure 2 illustrates in perspective a second embodiment in accordance with the present invention.

In accordance with the embodiments illustrated herein, the center cell of a cell-type vehicle consists essentially of the body top portion with roof part 1 or 1a and the side walls 2 or 2a integral therewith. The side or lateral body walls 2 extend forwardly and rearwardly of the roof 1 on both sides of the vehicle a substantial distance beyond the roof 1, the forwardly extending lateral body walls and the rearwardly extending body walls being each interconnected by an arched panel portion respectively. According to the embodiment of Figure 1, this upper part can be a single pressed piece or, according to the embodiment of Figure 2, for example, may be further subdivided along the longitudinal center plane. Essential is that the transverse closing walls 3 and floor 4 be separate from the upper part and form an independent base portion. The two parts 3 and 4 can be fastened together in any suitable way and, for example, may form one piece or may be assembled of separate parts, for example, by welding, the transverse closing walls 3 extending at a finite angle, such as for example, degrees,-

with respect to the floor member 4.

As the figures show, the shape of the body upper part is relatively simple. It is interlocked or interfitted in a particularly favorable way, as far as strength is concerned, with the bottom consisting of the floor and the transverse walls as shown in Figure 2. The car body shown in Fig. 2 is different from that of Fig. 1 in that it is provided with longitudinal panel strips 5 closing the bottom of the door apertures.

What I claim is:

1. In a car body of the cellular type construction a substantially self-enclosed center cell comprising an upper portion and a lower portion, said upper portion including a roof and forwardly and rearwardly extending lateral body walls integral with said roof and extending forwardly and rearwardly thereof on both sides of the vehicle a substantial distance beyond said roof and substantially arched panel portions connecting said forwardly extending lateral walls with each other and said rearwardly extending lateral walls with each other, the forwardly extending walls and the rearwardly extending Walls being connected with each other respectively, said lower portion including a substantially flat rectangular floor member and transverse end walls extending at a finite angle with respect to said floor member, said transverse walls being of substantially equal shape to fully enclose the space between the said respective lateral walls and the connections therebetween by said substantially arched panel portions at both ends of the center cell.

2. A car body according to claim 1 wherein the respective peripheries of said two portionsabut against each other in assembled position.

3. A car body according to claim 1 wherein at least one of said lateral walls is partly cut away to provide a doorway.

4. The combination according to claim 1, wherein both said upper and lower portions are made of artificial resinous material.

5. The combination according to claim 4, wherein said transverse end walls are substantially perpendicular with respect to said floor member.
